Anthropogenic Climate Change Exists

I thank my opposition for accepting this debate. This discussion is about Climate Change Anomalies from the years 1900 to 2200 (see comments section), and whether they are anthropogenic. Anomalies are deviations from "schedule" weather cycles, and can include both hot and cold extremes, making "global warming" only half of this discussion. So, right off the bat, temperature anomalies began rising just after the year 1900 [1]. http://climate.nasa.gov...; /> As shown in the following chart [2], this corresponds closely with a recent rise in CO2 emissions. This chart shows that CO2 levels have always travelled in cycles, but broke their most recent scheduled downward cycle to reach their highest level in over 400,000 years. In a sense, one might say nature did half the work on CO2 and the human race took it from there. http://climate.nasa.gov...; /> Correllation is obviously not causation, but the mechanics that link CO2 to temperature have been well documented. Atmospheric Greenhouse Effects: A Review [3] CO2 does not deflect visible light, which is what originally makes it to the earth's surface. Upon reaching the earth's surface, visible light is partially absorbed by the earth or water, and partially reflected. The reflection process lowers its energy level, turning it into infrared light. CO2 deflects infrared light. So CO2's reflective properties for the earth are one-directional. Visible light pass downward unperturbed, but upward infrared is deflected downwards / sideways. This effectually increases the amount of light striking the surface of the planet, which at current greenhouse levels protects life from the freezing cold of space, and at future levels threatens to roast life - not to death, but to ecological disequilibrium. http://climate.nasa.gov...; /> Oceanic Greenhouse Effects: A Review The oceans currently absorb atmospheric CO2 and are undergoing a resulting drop in pH. They are also currently absorbing most of the extra heat from the sun, and therefore are experiencing a rise in temperature. Once they heat to a certain point, the oceans are expected to start releasing CO2 back into the atmosphere, which may include massive reserves that have been down there for millions of years. However, before the oceans can truly begin warming, the ice caps have to melt. http://arctic.atmos.uiuc.edu...; /> And as we can see here [4], though the ice caps have shown about a half-century lag behind the thinner, more responsive atmosphere, they are roughly 1 million square kilometers smaller than they ought to be, as of 2014. It appears that climate anomalies are closely associated with CO2 levels, that CO2 levels are primarily anthropogenic and will continue to be so until the next 'natural' CO2 spike roughly one hundred thousand years from now (chart 1), and that the greenhouse mechanisms behind all this are straightforward and established. 1. http://climate.nasa.gov... 2. http://climate.nasa.gov... 3. http://climate.nasa.gov... 4. http://arctic.atmos.uiuc.edu...
